问题是什么

想使用maven 3.9.6 和 jdk21打包，自定义了agent，Dockerfile内容如下：

FROM eclipse-temurin:21-jdk

RUN apt-get update \

&& apt-get install -y ca-certificates curl git openssh-client –no-install-recommends \

&& rm -rf /var/lib/apt/lists/*

# common for all images

jenkins-casc-config的jenkins_user.yam内，添加了如下内容：

                      path: settings.xml

jenkinsfile流水线如下：

pipeline {

agent {

    node {

      label 'mavenjdk21'

   }

}

environment {

           KS_SPACE = 'dev'

           DOCKER_CREDENTIAL_ID = 'harbor-id'

           GITHUB_CREDENTIAL_ID = 'github-id'

           KUBECONFIG_CREDENTIAL_ID = 'kubeconfig'

           REGISTRY = 'harbor.ktiis.com'

           DOCKERHUB_NAMESPACE = 'cdb'

           GITHUB_ACCOUNT = 'wangzongce'

           APP_NAME = 'manage-center-start'

           ALIAS_NAME = '管理服务'

}

stages {

    stage ('build & push') {

        steps {

            container ('maven') {

                sh 'mvn  -Dmaven.test.skip=true -gs \`pwd\`/ops/configuration/settings.xml -U clean package'

                sh 'cd $APP_NAME && docker build -f Dockerfile -t $REGISTRY/$DOCKERHUB_NAMESPACE/$APP_NAME:$KS_SPACE-$BUILD_NUMBER .'

                withCredentials([usernamePassword(passwordVariable : 'DOCKER_PASSWORD' ,usernameVariable : 'DOCKER_USERNAME' ,credentialsId : "$DOCKER_CREDENTIAL_ID" ,)]) {

                    sh 'echo "$DOCKER_PASSWORD" | docker login $REGISTRY -u "$DOCKER_USERNAME" --password-stdin'

                    sh 'docker push  $REGISTRY/$DOCKERHUB_NAMESPACE/$APP_NAME:$KS_SPACE-$BUILD_NUMBER'

                }

            }

        }

    }

}

    stage('deploy to server') {

              steps {

                 container ('mavenjdk21') {

                              withCredentials([

                                  kubeconfigFile(

                                  credentialsId: env.KUBECONFIG_CREDENTIAL_ID,

                                  variable: 'KUBECONFIG')

                                  ]) {

                                  sh 'envsubst < /ops/dev/deploy/devops-sample.yaml | kubectl apply -f -'

                                  }

                            }

              }

        }

}

}

执行到最后一步stage(‘deploy to server’)后失败，报错如下：
